  • Gas sensor
    Patent number: 6514397
    Abstract: An exhaust gas sensor includes a first electrode, a second electrode, and an electrolyte disposed between the first electrode and the second electrode. The electrolyte includes a first portion disposed at least in partial physical contact and in ionic communication with a second portion. The first portion has a first portion grain size which is different than a second portion grain size. Further, a method for manufacturing a gas sensor includes forming a multiple portion electrolyte. The electrolyte is formed with a first portion having one grain size, and a second portion at least in partial physical contact and in ionic contact with the first portion, the second portion having a second portion grain size different from the first portion grain size. The electrolyte may be fired before or after application of an electrode in ionic contact with the first portion and a second electrode in ionic contact with said second portion.
